One more factor to evaluate (and then some),
Amazon Verified Purchase(What's this?)Please be aware that this unit is a 60-Hz. You would be hard-pressed to learn this from the specs and reviews.
While 120-Hz units cost more, and reduce blur, the quality of this 60-Hz unit is adequate, especially at this price. All TV signals are broadcast and/or recorded in 60-Hz. Thus, any 120-Hz or 240-Hz unit is not receiving/displaying a higher-quality signal, but merely interpolating the time-slices between the 60-cycle images (a digital scrubbing, as it were), to reduce blur.
Probably info overload, but I just wanted to say that it's a 60-Hz unit, in case anyone is looking for that spec. Wikipedia has an article on "HDTV blur" (section 100 Hz+) that explains it all.
Revision, about a month after purchase: I am very happy with this unit. The product page on Amz. is a bit misleading re: "Clear Resolution Enhancer" (whatever that is). Amz indicates that this unit does not have it, but the manufacturer's shipping crate clearly states that this unit (like the EX640 unit) does have it. Specs constantly change; inquiring minds want to know. It seems to reduce the out-of-focus conditions on the old Hollywood DVDs that are just plain old VHS transfers. Nice!
Another thing: older analog SONYs let you "Fix Channel" (lock it) on, say, channel 3. This is for us folks that get all their broadcast signals from a cable box--which has all signals coming out of the box to the TV on, say, channel 3. This keeps the kids and spouse and dog from hitting the numeric channel numbers on the remote, and inadvertently going into a black-screen situation. And the subsequent troubleshooting, puzzlement, etc.... This unit has no such feature, altho you can manually go in and block all 141 other channels, so that the unit displays a "Blocked" message and jumps back to normal after a few seconds.
A freebie: If you are replacing a Sony TV, this unit will most likely respond to your cable company's remote (On, Off, Volume, Muting, etc) since you already programmed it for a Sony. You others, well, you probably would have had to reprogram your cable-box remote anyway.
Finally, the sound: This TV is over 3" thick, so it has room for some decent speakers. The sound is MUCH better than what I hear coming out of other people's ultrathin TVs, mainly cuz there's some good bass.
Tech note: If your DVD player is using a 3-wire Yellow-Red-White (composite) cable, REPLACE IT with 5-wire Green-Blue-Red (component) video if available + plus Red-White for Audio (or equally as good, a 1-wire HDMI cable, if the player has a jack for it). The video signal really is MUCH better; why corrupt your DVD signal with an inadequte cable? A cheap fix.

I'm confused... are you saying that 60 - Hz is preferential to 120 - Hz? Please elaborate. Thanks!

Thanks. I've updated the review.

A. Person says:
I don't think he's necessarily saying that, but indeed people think 120, 240, etc... are truly refresh rates when really it's just tricks where mor frames are used, but the true refresh rate is 60.
I would say it's probably best to get a 120 over a 60, but I'm tempted to get a CCFL LCD like this anyway if I can't get these other tvs to stop bothering my head for some odd reason.

Blu-Ray players & many Video-on-Demand services utilize the higher refresh rates & your screen is much more life-like if it can handle 120Hz or better.

I checked Blu-ray on Wikipedia, and they say:
"High-definition video may be stored on BD-ROMs (i.e. Blu-Ray) with up to 1920×1080 pixel resolution at up to 59.94 fields per second (which is 60Hz), if interlaced. Alternatively, progressive scan can go up to 1920×1080 pixel resolution at 24 frames per second, or up to 1280x720 at up to 59.94 frames per second." But I agree that a 120-hz unit will smooth the jitters better.

You wrote a great review, very helpful, even for non-techie person such as myself. And thanks for the humor too :)
